1. What happens when you ping the 3Com nic from the "other PC".
I can see from the ifconfig that bytes are being
sent since TX packets is incremented, but that doesn't
mean they are getting to the wire.

2. What is the driver name ( use lsmod ).

post your /etc/sysconfig/network-scripts/ifcfg-eth0 file.

Is the NIC a dual ported one ? are you using the right port ? ;)
